Complete Roof Replacement After Decades of Deferred Maintenance
The Challenge
A 1978 Oakland Hills home had its original asphalt shingles still in place — nearly 46 years old. The shingles were severely granule-depleted, multiple valleys were leaking, the ridge had no cap shingles, and two layers of old roof existed beneath the surface. The homeowner had been patching for years, spending thousands on temporary fixes that never solved the underlying problem.
Our Solution
We completed a full two-layer tear-off, exposing the decking and discovering three sheets of rotted plywood near the north valley. Rotted decking was replaced with new 7/16" OSB, then the entire deck was covered with self-adhering ice-and-water shield (a best practice for Oakland Hills WUI fire zones). We installed GAF Timberline HDZ Charcoal architectural shingles rated Class A for fire resistance, new aluminum step flashing at all transitions, and a proper ridge vent system for attic ventilation.
The Result
The homeowner described it as 'a completely different house.' The new GAF system carries a 50-year limited warranty on materials and a 10-year workmanship guarantee from our team. Three months after installation, the first major Oakland rainstorm of the season produced zero leaks — the first dry interior the family had experienced in years.
